SPECIFICATION forming part of Letters aPatent Non.` 634,846, dated October 1'0, 1899..

Application led February 18,1899. Serial No. 706,061. (No model.)

To (LU who/it [t may concern:

.Be it known that we, CALVIN C. BOWEN and CHARLES R. TWITCHELL, citizens of the United States, residing at Los Angeles, in the 5 county of Los Angeles and State of California, have invented certain new and useful Im; provements in Animal-Traps, of which the following is a full, clear, and exact description, reference being had to the accompanying io drawings, which form a part of this speciiica tion.

Our invention relates to certain new and useful improvements in that class of animaltraps where the animal is killed by the oper in certain features of novelty hereinafter de scribed and claimed.

Figure I is a front elevation of our improved trap. FiO. II is a vertical section taken on 2o line II II, Fig. I. Eig. III isa side elevation.

Fig. IV is a rear elevation. Fig. V is a side elevation showing the opposite side of the trap from Fig. III. Fig. VI is a longitudinal section taken on line VI VI, Fig. IV, show- 2 5 ing the pneumatic check.

Referring to the drawings, l represents a base-block for supporting the various parts.

2 3 represent standards secured to the baseblock at their lower ends, said standards supporting certain mechanism of the trap. The lower ends of said standards arepreferably secured to the side of the block l by means .of a central screw 4 and by having inbent sec tions 5 of the standards driven into the side of the base-block.

6 represents a rod extending transversely of the trap and journaled near the upper ends of the standards 2 3, said rod G being formed in sections 7 S, having a sleeve 9, surround- 4o ing the rod, on which is mounted a coil-spring l0. Cnc end ofthe coil-spring l0 is secured at 1l to the section S of the rod 6, said section 8 being provided with a crank l2 for winding up or tightening the coilsof said spring.

13 represents a catch or lug on the outer side of the standard 2, said lug limiting the backward movement of the crank l2 when the spring has been wound up.

lt represents a crank on the section 7 of the rod 6.

l5 represents a piston-rod having its upper end pivoted at 16 to the crankli, said rod l5 being formed in U shape and extending into a pneumatic checking-cylnder 17.

1S represents aiiisk on the lower end of the piston l5, and 19 represents a valve secured on the under side of the disk 1S. The cylin der 17 is pivoted to one end of a rod 20, said rod 2O extending transversely of the trap and tends outwardly from the rod (5 in the direction opposite to that of the striker. 21.

25 represents a table for discharging the trap, said table being mounted on the inner end of a bent rod 26, which is provided at its opposite end with a trigger 27.

28 represents staples by which the bent rod 26 is pivoted to the baseblock l.

29 represents a spring having its loose inner end 30 resting upon the base-block l and having its opposite end attached at 3l to the rod 26, which supports the table 25, said spring normally holding the table 25 in a raised position. l

32 represents a lever having its upper end vpivoted to the standard 3, as shown at 33,

there being a short arm 34 on said lever eX- tending above the pivotal point'33. lVhen the trap is set, the lower end of the lever 32 engages the inner end of the trigger 27, as shown at 35, at which time the lower end of the pin 2i comes in contact with the short arm of the lever 32, as shown at 36,

37 represents brackets secured at 3S to the rear vend of the base-block l.

39 represents a striking-block pivoted at Li0 to the brackets 37.

Lil represents a spring having its upper end bearing against the rear face of the block 39 and its lower end secured at i2 to the base- IOO cape of odor from the same.

block l, said spring 4l serving to normally hold the block 39 in a vertical position, but which permits it to bend backward, as shown in dotted lines, Fig. V, when the striker re- 5 volves.

43 represents a bracket on the standard 2, which is preferably bent inwardly and extends parallel with the standard.

44 represents abaitholder,preferably made Io cylindrical in form and supported by the 2o 3, which limits the upward movement of the lever 32.

rlhe operation is as follows; The spring l0 is wound up by the crank l2 to a sufficient degree, the trap being set by the lower end of the lever 32 coming in contact with the trigger 27 and the pin 24 coming in contact with the upper end of said lever 32. When the animal steps upon the table 25, depressing the same,'the trigger 27 is correspond- 3o ingly depressed, as shown in dotted lines, Fig.

V, permitting the lower end of the lever 32 to fly upwardly,which lever permits the lower end of the pin 24 to pass over the top of the lever 32, thus permitting the striker 2l to 35 make one revolution, the striker knocking the animal against the block 39 and killing it. The block being pivoted recedes in front of the striker and permits the striker to continue its revolution, the block being normally returned 4o to its upright position by means of the spring 4l. As soon as the weight is removed from the table 25 the spring 29 raises it upwardly into its normal position, which also raises up the trigger 27 in position to catch the lower end of the lever 32, and as the striker continues to revolve the pin 24 comes in contact with the upper end of the lever and the striker is locked in the position as shown in Fig. I until the table is again depressed and the op- 5o eration repeated.

To prevent too much lateral and -vertical play of the spring 29 and table 25, I provide a staple 47, that limits the upward movement of the rod 26, and also provide bends 48 49 in 'the spring29 and rod 26, said bends allowing said spring and rod to fit down upon the rod 20, and thus limiting the downward and lateral movement of said parts. The base-block 1 is also cut away, as shown at 50, to permit 6o the movement of the trigger 27 and lever We claim as our invention- 1.
